Abstract: A sealed sterile intravenous catheter and needle assembly providing a substantially closed and sterile environment. The sealed sterile intravenous catheter is removably secured to a needle assembly and includes a tubular catheter portion, a catheter nozzle portion, and a gel cap portion aligned axially about a central axis to form a sealed flow passageway therethru. The gel cap portion includes a hollow gel cap hub having a gel cap formed of an elastic material to substantially seal the gel cap portion of the sealed catheter. Additionally, the needle assembly includes a needle configured to matingly cooperate with the sealed catheter assembly and pierce through the gel cap and sealed flow passageway of the sealed catheter assembly in a fully extended position. The needle will also be structured to fully retract for safe disposal after use.
